GE IS220PAICH1B Analog I/O module
Description：
IS220PAICH1B is part of GE Mark VI series analog I/O module. As a second version of PAIC units, the minimum voltage of this module is 22v, which is the difference between it and the first version of the PAIC units.
The Analog Input/Output (PAIC) pack provides the electrical interface between oneor two I/O Ethernet networks and an analog input terminal board. The pack containsa processor board common to all Mark* Vle distributed I/O packs and an acquisitionboard specific to the analog input function. The pack is capable of handling up to 10analog inputs, the first eight of which can be configured as +5 V or +10 V inputs, or 0-20mA current loop inputs. The last two inputs may be configured as +1 mA or 0-20 mAcurrent inputs. The load terminal resistors for current loop inputs are located on theterminal board and voltage is sensed across these resistors by the PAIC. The PAICH1also includes support for two 0-20 mA current loop outputs. The PAICH2 includes extrahardware to support 0-200 mA current on the first output.
Input to the pack is through dual RJ45 Ethernet connectors and a three-pin power inputOutput is through a DC-37 pin connector that connects directly with the associatedterminal board connector. Visual diagnostics are provided through indicator LEDs.
PAIC will mount on a TBAIH1A or TBAIH1B terminal board the pack will not realize full accuracy of the analog signals due to circuit differences between the terminal board revisions. For this reason, the PAIC is only compatible with the H1C version of IBAI and will report a board compatibility problem with any of the earlier revisions. No physical damage will result if a PAIC is powered up on an older board in error.
